The Museum of Santa Croce in Florence, Italy, occupies the former refectory and wing of the Franciscan convent that separated two cloisters. It includes the celebrated Pazzi Chapel, a “God the Father” statue by Bacio Bandinelli, Taddeo Gaddi’s “Lignum Vitae,” Donatello’s “St. Louis of Toulouse,” and Giorgio Vasari’s “Last Supper.”
